the virulence of four iranian isolates and one exotic isolate of beauveria bassiana on the fifth instar nymphs and also five iranian isolates and one exotic isolate of it on the adults of eurygaster integriceps puton was studied using dipping and topical micro-application techniques, respectively. nymphs were highly susceptible to the isolates. comparison of lc50 values showed no significant di...

to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...

background : helicobacter pylori ( h. pylori ) infection is known as a major etiologic factor for a variety of gastroduodenal diseases. in iran, with a high rate of h. pylori infection close to 90%, numerous studies have revealed many aspects of interaction between the bacterium, mucosal surface and induction of disease outcome. the organism is genetically diverse and several virulence factors ...

background shiga-toxigenic escherichia coli is an important human pathogen cause of diarrhea, hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans is a significant public health. objectives the aim of this study was to determine the molecular characteristics and antimicrobial resistance properties of shiga toxigenic escherichia coli (stec) strains wit...

Sugérese que la hiperuricema sea un factor de riesgo cardiovascular en humanos adultos con síndrome metabólico (SM) El polimorfismo C677T en el gen metilenotetrahidrofolato reductasa (MTHFR) ha sido asociado com la hiperuricemia. Datos sobre los factores asociados con la uricemia en humanos adultos con SM genotipados para el polimorfismo C677T en el gen MTHFR son inexistentes. Se objetivó inves...

Resumen.—La teoría sobre historias de vida sugiere que las especies de aves longevas ajustarán su esfuerzo de anidación de acuerdo a las condiciones actuales para balancear los costos y beneficios de la reproducción actual con sus necesidades de largo plazo en relación con la supervivencia y la reproducción futura. Sin embargo, las respuestas a las mismas condiciones del hábitat pueden diferir ...

Superada la pasión healthy por la salud individual y la obsesión por la salud como un objetivo en la vida, se está consolidando un nuevo modelo en promoción de la salud relacionado con lo que es favorable y positivo para la salud. Esta nueva concepción de «salud positiva» emerge frente al modelo tradicionalmente imperante en salud pública que se centra en la protección y la prevención, y pone é...

the bacterium oceanimonas sp. (o. sp.) gk1 is a member of the aeromonadaceae family and its genome represents several virulence genes involved in fish and human pathogenicity. in this original research study we aimed to identify and characterize the putative virulence factors and pathogenicity of this halotolerant marine bacterium using genome wide analysis. materials and methods: the genome da...

Pathogenic Escherichia coli strains cause a wide range of extra intestinal infections including urinary tract infection in humans and colibacillosis in poultry. They are classified into uropathogenic E. coli (UPEC) and avian pathogenic E. coli (APEC) with genetic similarities and variations. Their pathogenicity is related to the virulence-encoding genes like sfa</...

conclusions results of the present study showed that the tst and sea genes had high frequencies among the mrsa isolates. the increased prevalence of mrsa isolates containing different virulence genes, probably accompanied by antimicrobial resistance, can complicate the therapy of mrsa isolates. results all the tested isolates were susceptible to vancomycin, but resistant to penicillin (100%), e...
